Application filed .lanuaiy :26y 1911. Serial No. 604,886.

if the cream Iron; the body oi milk contained within a` vessel `andincluding' Ineens whereby the cretini muy be etlectuelly removed'vif'itliout ren'ioving; the milk irrespective of the thickness o1 thecream.

'lilith the above object in view the device includes o cylindrical bodyin which is mounted a slidable pist-on.' The intermediate portion ot eSiphon tube is secured to the lower portion of Ythe seid body and the .ashorter ot the said tube is provided with :in adjustable sleeve through'which the cream is drown trom the body of milk without refer-d to thethickness or dept-h of the volume oi cream.

ln the accompanying drawingzlzligure 1 is e sectional view ot' thedevice. Fig. 2 is o. horizontal sectional view oi the suine cui; on theline 2-2 of Fig. 1.

fis liereinoeiof'e stated the device is esbe used for removing the creamfrom. o body of milk and furtherinore it is adapted @speci-elly to beused in conjunci on 'with the ordinary milk bottles now used forserving)T milk from a dealer to The device consists ot' a cylindrical.body in' in its interior and in the vicinity of i end e Hnge Q. Thebody l is open lo et its lower end and within the lower end portion isadopted to receive the upper end of :i hottie 2% upon the top of whichwill rest Siphon after it has been adjusted. 'ille body Y1 immediatelyabove the intermediate portion oi' the Siphon 4 is slightly. swelledinfin outward direction es at 6. A piston 7 is slidnbly mounted in thebody l and fits snugly within the upper pbrtion thereof closing theseine dionietricelly. A stein or handle 8 is attached to the piston 7and posses through :i ruido provided :it the upper end of the body l.

ln operation the top portion of the bottle 3 is inserted. within thelower portion oi' the body l and the flange 2 rests upon the upper edgeof the said bottle. The shorter legof the Siphon l is projected downinto the creare contained within the bottle 3 until the lower end of theshorter leg` oi" the seid siphon is at the bottom of the cream. it thecreano varies in depth the sleeve may be adjusted upon the shorter legof the siphon soV that the iower end or the seid sleeve will be et thebottom of the cream. The piston 7 :it this 'time is at the upper end ofthe, body i. An operator then pushes the handle or stein S in e downwarddirection which carries with it the piston- 7 and the nir conte-inedwithin the body l 4below the piston 7 is compressed against the uppersurface of the cream contained within the bottle 3. This will Ytorce thecream up through the sleeve 5 and shorter ieg ot the siphon 4l over theintermediate portion of the seid siplion and down through the longer legthereof. Thus the Siphon started and when the piston or rives et theswelled portion 6 in the body the surface ot the cream contained withinthe bottle 3 is subjected to the pressure of the external atmosphere forthe reason thet the piston 7 does not t snugly Within the swelledportion 6 and consequently there is space between the edge of thepiston' and 'the inner side of the swelled portion 6. Therefore thesiplionage will continue until the surface of the cream is et or belowthe level of the lower 'end of the shorter leg of the Siphon i or itstube 5 when the Siphon will be broken and the cream is removed from thebottle 3 with out disturbing the milk. Nhile the present device isespecially adopted to be used for removing cream from :i bottlecontaining both crezun end milk it is to be understood that it may beused to advantage for other purposes where it is desired to remove aliquid from a vessel to a predetermined depth below the surface of theliquid oontained within the vessel.

Having described my invention what l Claim as neW and desire by LettersPat` ent is z- 1. A skimmer comprising an open ended body, said bodybeing diametrically en-l larged at a point between its ends, a Siphonpassing through the side of the body below the enlarged portion thereof,a piston mounted for reciprocation in the said body and arranged to passinto the said enlarged portion at the end of the stroke toward the openend of the said body, and a sleeve adjustably mounted on the shorter legof the Siphon.

2. A skimmer comprising an open ended body having in the vicinity ot'its lower end an inner annular flange, said body being diaxnetrieallyienlarged at a point between its ends, a piston mounted for reciproeationin the body and arranged to pass into the said enlarged portion at theend of the stroke toward the open end of the said body, and a Siphonpassing through the side of the body at a point above the the path ofmovement ot' said piston.'

3. A skimmer comprising an open ended body, said body beingdiametrically enlarged at a point between its ends, a Siphon passingthrough the side of the body below the enlarged portion thereof, and apiston mounted for reoiprooation in the body, the enlarged portion beingat the end of the stroke of the piston toward the open end of thesaidbody, whereby a space is created between the edge of the piston and thesaid body upon the piston heilig forced to the end of its stroke towardthe open end of the body.

ln testimony that I claim the foregoing as' my own, I have heretoaffixed my signature in the presence of two witnesses.`
